摘要
通过数值分析对土质边坡动力响应规律进行研究,发现在土质边坡剖面上动力响应参数分布异常的地方跟通常认为的潜在滑动面有很好的对应关系,说明在坡体内发生较大剪应变处土体的动力特性可能已经发生改变,从而使动力传递异常。
Using numerical analysis on the law of dynamic response of soil slope, it is found that there is a good corresponding relationship between the anomalous points of dynamic response and the location of potential sliding surface on soil-slope section. It shows that the dynamic property of soil where high shear strain has happened may have changed in the slope, and caused the dynamic transmission abnormal.
